Answer:

There is no solution.

Step-by-step explanation:

-4x+y = -6 rearranged to slope intercept form would be y = 4x-6 because slope intercept form is y = mx+b where m is the slope and b is the y-intercept. Also, when the x has to swap to the other side of the equal sign, it will change from negative to positive, or vise versa. Then, 8x-2y = 14 would be y = 4x-7 because if you divide 8x, -2y, and 14 by -2 in order to isolate your y, the equation would turn into -4x+y = -7. Again, rearrange it to slope intercept form. Now that your equations are both in slope intercept form, you rewrite them without the ys. Which means, 4x-6 = 4x-7. However that is not true. To further explain, you can subtract 4x from each side of the equal sign, leving finally -6 = -7. And that is still not true. Therefore, the final answer would be no solution.

Which inequality can be used to explain why these three segments cannot be used to construct a triangle?

ryzh [129]

The answer choice which explains that the three segments cannot be used to construct a triangle is; AC + CB < AB.

<h3>Which inequality explains why the three segments cannot be used to construct a triangle?</h3>

Since, It follows from the triangle inequalities theorem that sum of the side lengths of any two sides of a triangle is greater than the length of the third side.

Hence, since the sum of sides AC + CB is less than AB, it follows that the required inequality is; AC + CB < AB.
